v0.14.0 — Optional Muse Code and OpenCode 2

Setup → Agents now offers optional Muse Code installation and OpenCode 2 in the existing OpenCode version picker.

• Muse Code: install only when requested, sign in with a Meta device code or save an API key, and keep credentials on the persistent volume. T3 Code checks Muse sign-in on the first message; saved credentials alone are not reported as verified.
• OpenCode 2: choose Install a specific version… on the OpenCode row and search for 2. The official @opencode/cli package is installed through mise. Updates stay within the selected major, and a failed switch preserves the previous selection.
• Defaults: the image starts with T3 Code Stable and OpenCode 1; Muse is excluded from the default first-start installs. Using Muse or OpenCode 2 in T3 Code requires Nightly, selectable under Setup → Environment.

OpenCode 2 requires version 2.0.18 or newer. Before switching majors, stop running OpenCode sessions and back up its data. OpenCode 2 converts the shared database on first use; installing an older CLI does not restore that database. The setup panel explains this before starting the switch.

Update the container image to v0.14.0 to get the new setup panel and installer support. T3 Code itself continues to support in-container Stable/Nightly switching.

Images for Linux amd64 and arm64:

• Browser: ghcr.io/dizys/t3code-docker:0.14.0 or :0.14.0-browser
• Core: ghcr.io/dizys/t3code-docker:0.14.0-core
• The latest, browser, full, core, and slim tags point to this release.

All 387 Node tests pass, including Muse CLI dispatch regressions. Release CI passed both image variants on both architectures, including native smoke tests and the amd64 agent lifecycle tests. Published manifests and image version/source labels match the tested release digests. Real ARM64 CLI lifecycle and desktop/mobile setup panel flows were also verified locally.
